ICEpower125ASX2 is now released for sale! – December 6, 2007

True to the ICEpower brand promise, the 125ASX2 delivers industry-leading audio performance, efficiency and power density, enabled by the latest ICEpowers technological breakthroughs.
ICEpower125ASX2 module replaces the traditional amplifier and power supply assemblies in a range of applications, some of which are listed below:

Stereo amplification, Active speakers and subwoofers, Audio systems in performance flat-panel TV, Musical instruments, Professional speakers and studio monitors.

Small size, Big power
ICEpower125ASX2 delivers the power output of: 500W at BTL, 4 ohm, 10% THD+N, 2 x 125W at SE, 4 ohm , 1% THD+N with the dimensions of only 16 x 8 x 3.5 cm (6.3 x 3.1 x 1.4). The mechanical outline features a uniform slim width and a uniform low building height. The power density exceeds 20W per in, which combined with the unique geometries of the ASX2 Series, open up new innovation space for audio manufacturers.
Total efficiency of 125ASX2 exceeds 86% (BTL, 250W, 8 ohm), which secures cool operation and enhances product reliability. Combined with the low idle consumption, which is 5-10 times lower than that of comparable Class AB amplifier assemblies, 125ASX2 is a responsible choice when caring for the environment.

Innovation Freedom
Flexibility is paramount to the ASX2 Series. 125ASX2 can be combined with the other modules in the Series as application building blocks to generate a wide variety of 1-8 channel audio applications in consumer, professional and multimedia audio products.
